Micro 830 RTC Timed Events

I have the Allen Bradley Micro 830 and I am trying to setup a daily and weekly event that occurs at a certain time. It looks like the Micro 830 supports and external RTC module. I do not have that module and need this functionality without purchasing one. Is there anything else I can do to trigger on these time events based on the current time?

how are you going to set the value or check the value?
Are you using a HMI?
the altenative is to setup a one sec. Pulse. then setup multiple counters to stage the switch point.
but the only way you will see this is if you are interogating the PLC.
